From 96f845de89be6be12112d7b388cdf366dccfe12d Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sat, 29 Aug 2009 00:49:36 +0200 Subject: [PATCH] ALSA: hda - Create "Digital Mic Capture Volume" correctly for IDT codecs So far, the digital mic capture volume wasn't created. This is because IDT codecs have output amps for digital mics, not input amps, while input amps should be used for other analog pins. Thus the automatic capture volume creation should check both directions for digital mics.
